Kemperol 1K-PUR

A single-pack roof repair system designed for use on a wide range of substrates, to provide a homogeneous, seamless waterproofing membrane. Suitable for small flat roofs, general detail work and repairs. The lightweight nature of the system adds minimal load, making it particularly useful when roof stability is a concern. It is cold liquid-applied straight from the can and rain resistant in 30 minutes. The system is reinforced with polyester fleece. Structural details are protected without additional flashings or other mechanical fixings.
